How exciting and nerve-racking all at the same time!
Well, the biggest thing for me is to breathe lol! I need to count to 10 every time I go into the ring!
I think if you look at it as more of a fun thing then you wont have the nerves to worry about and can focus on making the dog look good.
All easier said than done!
Best of luck to you! I am sure you will do just wonderfully! You will have to keep us posted on the results!
